Abstract
An improved microelectromechanical switch assembly comprises a linearly movable switch rod constrained via a switch bearing, the switch rod being actuated by electrostatic deflection. Movement of the switch rod to one end of its travel puts the switch assembly in a closed state while movement of the switch rod to the other end of its travel puts the switch assembly in an open state. In an embodiment of the invention, one or both of the switch rod and the switch bearing are fabricated of a carbon nanotube. The improved microelectromechanical switch assembly provides low insertion loss and long lifetime in an embodiment of the invention.
